The ODF file extension is known as OpenDocument Formula which was created by OpenOffice.org Math. It is a file format that saves the text used for creating the formula as well as mathematical equation. Formatted results can be printed to a .pdf file. They are based on the OASIS OpenDocument standard.
OpenOffice.org can import Microsoft Office files. However, at the time of writing, Microsoft Office cannot import files in the OpenDocument format used by OOo. Users of MS Office 2000, XP, 2003, and 2007-SP1 can install an ODF plugin from Sun Microsystems that enables Microsoft Word, Excel and Powerpoint to read and write OpenDocument files.
